Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602220, here are decompositions:

3 + 31602217 = 31602220
47 + 31602173 = 31602220
149 + 31602071 = 31602220
179 + 31602041 = 31602220
233 + 31601987 = 31602220
347 + 31601873 = 31602220
383 + 31601837 = 31602220
401 + 31601819 = 31602220

Showing the first eight; more decompositions exist.
